Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00813 (0.00533 - 0.01241), b=3.08 (2.96 - 3.20), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 3.6 ±0.1 se; Based on diet studies.

Resilience (Ref. 69278): Very Low, minimum population doubling time more than 14 years (K=0.09-0.2; tmax=37; tm=3-7;).

Prior r = 0.31, 2 SD range = 0.14 - 0.69, log(r) = -1.17, SD log(r) = 0.4, Based on: 3 K, 4 tgen, 1 tmax, records

Vulnerability (Ref. 59153): High to very high vulnerability (70 of 100) .

Price category (Ref. 80766): Medium.
